120-Volt Electrical System
Shore Power
When your trailer is hooked up to
external AC power, the converter
system automatically charges the
trailer battery(s) with the battery
disconnect switch in the ON position
and, if the 7-way cord is hooked up and depending
on your vehicle, your tow vehicle battery as well.
The speed and degree of charge depends on how
much power is used for lights and appliances, as
only the surplus goes to charging the battery. If you
are making an extended stay, then you should keep
your trailer hooked up to a 120-volt current if it is
available.
While you are connected to the 120-volt receptacle,
the wiring is protected by circuit breakers in the
breaker panel. The circuit breaker panel for the 120-
volt system is in the converter. Open the converter
door. In the event of a failure of a 120-volt circuit,
first check your trailer circuit breakers and the
breaker for the outlet into which your trailer
shoreline cord is plugged. If a breaker continues to
trip after you have reset it several times, your circuit
may be overloaded with appliances or there may be
a short in the circuit. Try lessening the load on the
circuit. Perhaps an electric griddle, hair dryer, or an
electric heater can be turned off. If that does not
solve the problem, consult an
nüCamp RV
Service
Center.
T
he 120-volt electrical system provides power to
operate the air conditioner, converter, and 120-volt
receptacles for portable appliances. The power is
carded through the 120-volt city power flexible cord
to the 120-volt distribution panel, and then is
distributed to each appliance or receptacle.
All wire, components, and wiring methods conform
to federal and state requirements.
Converter
The converter system enables you to use the 12-volt
lights and equipment whether operating on self-
contained battery power or hooked up to 120-volt
city power. The 12-volt light bulbs give off the
same light as regular household bulbs, so that when
operating on self-contained battery power,
everything works normally except the 120-volt
convenience outlets and 120-volt appliances.
NOTE
When operating with city power, make very
certain that the service is 120-volt and not 240-
volt.
The converter system is a transformer designed to
maintain constant output voltages regardless of the
variances that occur in city power systems. The
design eliminates the need for complex electronic
sensing systems to charge the batteries, minimizing
the possibility of failures and greatly increasing its
overall reliability.
In some older parks and other locations where three
pronged outlets are not available, certain
precautions to ensure proper grounding and polarity
must be taken. These precautions are listed below:
1. Attach the three-pronged plug to a two-pronged
adapter. The third conductor line of this adapter has
a short wire lead, that must be grounded.
2. For proper grounding, connect the short ground
lead to a grounded outlet box or to a cold-water
pipe. When no water pipe is available, drive a metal
rod two feet into the ground and attach the ground
lug to it, thus, providing the unit with proper
grounding.
NOTE
When the three-pronged plug can be used, there
will be no problems with proper polarity or
grounding with a properly wired shoreline
outlet.
